As has been alluded to, the difference between CDG and AMS is cultural. If your business is not francophone oriented then you don't need CDG, a lot of the interconnect options there are francophone - Africa, Canada, Caribbean, etc.
As someone said, we are not polyglot, more's the pity.
Of course AER L's insistence on staying in the archeological glacial age that Term 1 in CDG represents doesn't help.
